T 0 all whom it may concern Be it known that T, Gnonon CARTER, a subject of the King of Great Britain, residing at Calgary, in the Province of Alberta, in the Dominion of Canada, have invented certain new and useful Improve ments in Devices for Raising and Lowering Windows, of which the following is a specification.

My invention relates to improvements in devices for raising and lowering windows, and the object of the invention is to devise means connected to both of the sashes for raising or lowering both sashes simultaneously.

A further object is to provide improved means for raising and lowering the upper sash alone, and a still further object is to provide improved means for raising and lowering the lower sash by itself.

The invention consists of upper and lower sashes, pulleys secured to the underneath surface of the upper horizontal portion of the window frame near each side of the same, pulleys suitably secured to the lower sash at the top and near the sides of the same, upwardly turned hooks secured to the lower sash below the pulleys, guiding hooks secured to the lower sash below the hooks, guiding hooks secured to the upper surface of the lower horizontal portion of the window frame near the sides of the same, hooks secured to the upper surface of the lower horizontal portion of the window frame in front of the guiding hooks, and chains connected to the sides of the upper sash and extending up through the pulleys on the underneath side of the upper horizontal portion of the frame and down through the pulleys on the lower sash, through the guiding hooks below the pulleys, and also through the guiding hooks on the upper surface of the lower horizontal portion of the window frame, all as hereinafter more particularly described, and illustrated in the accompanying drawing in which Figure 1 represents a perspective view of a window frame and sashes to which is applied the device constructed according to my invention. Fig. 2 is a perspective detail of one of the pulleys secured to the lower sash, and one of the upwardly turned hooks underneath the same showing a portion of the chain running through the said pulley. Fig. 3 is a perspective detail showing one of the Specification of Letters Patent.

Serial No. 760,33

guiding hooks secured to the upper surface of the lower horizontal portion of the window frame and also showing one of the hooks in front thereof as well as the chain running through the said guiding hook.

Like characters of reference indicate cor-- responding parts in each figure.

1 is the window frame, and 2 and 3 are the upper and lower horizontal portions thereof respectively.

1 is the upper sash and 5 is the lower sash.

G are the pulleys suitably secured to the underneath side of the horizontal portion 2 of the window frame 1 near the sides thereof.

7 are the pulleys secured to the lower sash 5 near the top and sides thereof.

8 are the upwardly turned hooks below the pulleys 7.

9 are the guiding hooks below the hooks 8.

10 are the guiding hooks secured to the surface of the lower horizontal portion 3 and 11 are the hooks in front of the said guiding hooks 10.

12 are the chains suitably secured at one end to the upper sash 1- and extending up around the pulleys 6 and down through the pulleys 7, the guiding hooks 8, and around the guiding hooks 10.

The operation of the device is as follows: When it is desired to open both sashes the chains 12 are grasped between the pulleys 7 and the guiding hooks 9 and pulley at an angle outwardly. This will raise the lower sash 5 and if the chains 12 be hooked over the hooks 8 the sashes being of equal weight will counter balance each other and may readily be run into a position so as to coincide with each other, or if itis desired to have the upper sash more open than the lower one or vice versa the chains may be hooked over the hooks 11 and the sashes thus held in any desired position. To close the sashes the chains are removed from the hooks 11, and the hooks 8, and drawn down until the upper sash 4: is closed, the lower sash running down into a closed position of its own weight. The chains are then hooked over the hooks 8 and the hooks 11 to hold both sashes in a closed position. When it is desired to open the lower sash alone the chains are held outwardly at an angle and pulled until the lower sash has reached the required height. They are then hooked over the hooks 8 and 11. When the chains are released from the hooks 8 and 11 the lower sash will close of its weight. To open the upper sash the chains are removed from the hooks 8 and the hooks 11, when the sash will open of its own weight. W' hen opened a requisite extent the chains are hooked over the hooks 11. To close the upper sash the chains are pulled until the upper sash is closed when they are hooked over the hooks 8 and 11 in order to hold both sashes closed. The sashes will be also incapable of being opened from the outside when the chains are hooked over the hooks S and 11.

What I claim as my invention is:

A raising and lowering device for windows comprising in combination with the upper and lower sashes and the window frame, pulleys suit-ably secured to the upper horizontal portion of the window frame,

pulleys suitably secured to the lower sash, guiding hooks secured to the lower sash, hooks suitably secured to the lower sash beneath the pulleys on the same, hooks suitably secured to the lower horizontal portion of the window frame, guiding hooks secured to the lower horizontal portion of the window frame, chains secured to the upper sash and extending up around the pulleys secured to the upper horizontal portion of the window frame and down through the pulleys secured to the lower sash, and through the guiding hooks.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

GEORGE CARTER.
